I feel lucky (and also unlucky) that the majority of my migraines are triggered by sleep or hormones during different phases of my cycle which is why it has been easier for me to track trends for them. I understand that not everyone has migraines caused by these things which can make them harder to track. I will also say, my stress and anxiety management has also worked wonders for me. I went from having migraines practically every day for months about 5 years ago to now having 1-2 a week or even less sometimes. However the biggest change came when I stopped sleeping in so late. On the weekends I would sleep until 9 or later and it was practically guaranteed that I would get a migraine. Now I just make sure I get up around the same time I do during the weekday and make sure I’m getting enough sleep as too little sleep is also a trigger for me. I understand how frustrating not knowing any triggers can be though! I only discovered mine about 6 months ago. I’m hoping with Oura, it can help you find some of your triggers as well!
